The present invention relates to machines for operating upon insoles forboots and shoes, and more particularly to a machine for trimming themargins of manufactured insoles such as are used in making standardizedwelt shoes.

In making such standardized shoes, automatic machinery is employed inwhich the operating instrumentalities and the shoe are Lnoved relativelythrough a predetermined path by mechanical means to transfer the pointof operation aronnd the shoe. To obtain satisfactory results by the useof such machinery, it is necessary that all insoles of the same size andstyle be alike in all dimensions, particularly with regard to therelation of the sewing-rib to the edge of the insole. An example of amanufactured insole, adapted for use'in a Welt shoe of the type abovereferred to, is disclosed in United States Letters Patent No.1,578,359,- granted March 30, 1926, on my application. The in soledescribed in said Letters Patent is of laminated construction, beingbuilt up of one or more body layers ofsheet insole material and anoutside layer, preferably of textile material, this layer having agrooved sewing-rib moulded therein. In order to provide material to formthe sewing-rib, the layer of textile material is died out to a largersize than the body layers,- it being intended to make such allowancefor'the sewing-rib, that when the rib has been moulded, the layer of textilematerial will be exactly the same size as the body layers. It has beenfound difiicult or impracticable uniformly to obtain this result andconsequently the relation of the sewing-rib to the edge of the insole isliable to vary in the completed insoles. To avoid this diiliculty, it isnow proposed to die out all of the component layers of the insolepreliminarily to such a size that, when assembled, the size of theinsole will be slightly greater than that ultimately desired andsubsequently to trim the insole to the requisite size having due regardto the desired location of the sewing-rib relative to its edge.

One of the objects of the present invention is to provide an efficientand reliable machine for trimi'ning the margins of Welt insoles so as toproduce an insole the sewing-rib of which Will bear a predeterminedrelation to theedge of the trimmed insole;

.VViththis object in view, one feature of the ii'ivention comprises thero-vision, a machine for operating upon welt insoles, of a knife fortrimming the margin of the insole, and a pattern adapted to guide theknife and locate the insole thereon by an engagement with its sewing-ribso that the margin of the insole will project beyond the edge of thepatteri'i to be traversed by the knife.- In the illustrated embodimentof this feature of the invention, the pattern comprises a flat plate,the edge of which serves to guide the trii'nming knife, while its upperface is recessed to receive the sewii'lg-rib of the insole as the latterisp'laced, ribbed face down, upon the pattern by the operator. Thepatternis constructed and arranged to support the" insole b engagementwith its margin and to locate t 1e insole relative to the path of theknife by engagement with its sewing-rib so that the trimmed margin willbear predetermined relation'to the previously formed sewing-rib. In thisWay the location of the trimming cut on the margin of the insole withrelation to the sewing-rib will be definitely determined.

l Velt insoles for standardized shoes- Such as above referred to areprovided with a pair of jig-holes punched through their heel-seatportions. These jig-holes are adapted to receive a pair of pins whichare provided on the last for locating the insole upon the last bottompreparatory to the performance of the lasting operation; In order thatthe insole may be properly located upon the last, it is necessary thatthe jig-holes be accurately located at predetermined points on theinsole. It is not practicable to punch the holes through the insole atthe time theseveral component layers of the insole are assembled,inasmuch as the layers are then in a heated state, and consequently areliable to shrink as they cool, with the result that the jig-holes willnot be uniformly located in different insoles; Neither is it desirableto punch the jig-holes by an entirely separate operation after shrinkagehas taken place on account of the additional time and expense requiredtherefor.

Another object of the invention is to provide, in a machine for trimmingthe margins of welt insoles, means for punching one or more jig-holes inthe insole. In carrying out the feature of the invention it is proposedto punch these jig-holes during the work-engaging movement of the clampby the pressure of a cutting-block, mounted upon the clamp, against apair of dies or punches carried by the pattern.

The invention further consists in the features of construction andcombination of parts hereinafter described and particularly pointed outin the appended claims, the advantages of which will be apparent tothose skilled in the art. 7

The various features of the inventionv will be best understood from adescription of the preferred embodiment thereof illustrated in theaccompanyingdrawings, in which the invention has been shown as embodiedin a machine which is similar, in its general characteristics, to thePlanet sole rounding machine disclosed in Letters Patent of the UnitedStates, No. 882,009, granted March 17, 1908, upon application ofBenjamin F. Mayo.

In the drawings, Figure 1 is a View, in front elevation, of the machine;Fig. 2 is a plan view, on an enlarged scale, showing particularly thepattern, the trimming knife and the mechanism for supporting andactuating the knife; Fig. 3 is a top plan view of the pattern, this viewbeing on a still further enlarged scale; Fig. 4 is an inverted plan viewof the clamp for holding the insole againstthe pattern; Fig. 5 is aview, in side elevation, of the pattern-and the clamp, the latter beingshown. in its raised or inoperative position and the pattern having aninsole resting thereon in position to be engaged by the clamp; Fig. 6 isa View similar to Fig. 5, showing an insole held against the pattern bythe clamp in position for the trimming operation; Fig. 7 is a detailedsectional View taken on the line 77 of Fig. 6;'Fig. 8 is a detailedperspective View of the trimming knife; Fig. 9 is a view, in frontelevation and on an enlarged scale, of a portion ofthe machineillustrated in Fig. 1, showing particularly the manner in which theclamp is supported; Figs. 10, 11 and 12.are detailed sectional viewstaken on the lines 1010, l111 and 1212, respectively, of Fig. 9; andFig. 13 is a detailed perspective view of one of the parts associatedwith the clamp.

As illustrated in Figs. 1 and 2 of the drawings, the pattern, which isindicated at 14, is held stationary by a pair of vertical posts 16,rising from a block 18 upon which the posts are mounted with provisionfor adjustment toward and from each other to enable them to supportpatterns of different sizes. The block 18 is rigidly secured to theupper end of a cylindrical standard 20 which is bolted to the base 22 ofthe machine.

During the insole rounding or trimming operation, the insole is securelyheld against the Pattern 14 by means of a clamp 24 carried by aclamp-carrier 26 pivotally secured to the lower end of a slide 28 thatis mounted for Vertical reciprocation in an overhanging portion 30 ofthe machine frame. The slide 28is connected to the forward end of anactuating lever 32, the opposite end of which is engaged by a rod 34which is connected with a foot treadle 36 in such a manner that thedepression of the treadle will actuate the slide 28 to force the clamp24 toward the pattern 14. The clamp is raised by means of a coiledspring 38 connected at one end to the lever 82 and at the opposite endto the frame of the machine.

The rounding or trimming knife, which is indicated at 40, is caused totravel around the pattern 14 by the rotation of a rotary support 42, thehub of which rests upon the hub of a stationary cam 44 that is fixedupon the standard 20. As bestshown in Fig. 2, the knife40 is secured toa holder 46 mounted at the end of an arm 48 rigidly secured to asegmental shaped plate 50 pivotally mounted at 52 upon a carrier 54. Thecarrier 54 is mounted to slide upon a guide 56 that is pivoted upon therotary support 42. The guide 56 is rocked and the carrier 54 movedinward and outward on the guide, as the rotary support 42 is revolved togive the proper movements to the knife, by means of the stationary cam44 and a second stationary cam 58 (Fig. 1) which are connected with theguide and with the carrier respectively.

The general arrangement of the above named parts and their mode ofoperation, so

far as already described, is the same as that set forth in thehereinbefore mentioned Letters Patent No. 882,009. With the exception ofthe pattern, the clamp-carrier and the rounding knife, which areespecially designed to accomplish certain of the ob jects of the presentinvention, the particular construction of all the parts above describedis or may be substantially the same as that of corresponding parts ofthe machine of said Letters Patent. The rounding knife is yieldinglyheld against the'pattern by mechanism substantially the same as thatwhich has been heretofore employed in machines of this generalcharacter, the construction of this means being described in thelastmentioned Letters Patent.

The rotary support 42 is driven to cause the trimming knife to travelaround the pattern, through a driving shaft 60 (Fig. 1) which isconnected with said support by means of a bevel pinion 62 fast upon theend of the driving shaft and engaging a beveled gear 64 secured to theunderside of the support 42. Motion is imparted to the driving shaftthrough speed changing mechanism indicated generally at 66 in Fig. 1.This mechanism 66 is substantially the same as corresponding mechanismdisclosed in Letters Patent of the United States, No. 1,048,511, grantedDecember 21, 1912, upon application of W. G. Eaton.

The pattern 14 and the clamp 24 of the machine shown in the drawings areconstructed and arranged for use in connection with manufactured weltinsoles in which the feather or sole margin is molded around the toe, asillustrated and described in the hereinbefore mentioned Letters PatentNo. 1,578,859. A manufactured welt insole having its feather molded atthe toe, as dis closed in said Letters Patent, is illustrated .at 68 inFigs. 5 and 6.

As shown in Figs. 3, 5, 6 and 9,. the pattern 14 consists of asole-shaped plate which is constructed and arranged to support theinsole during the trimming operation, while the edge of the plate guidesthe rounding knife and thus serves to determine the shape and size ofthe trimmed sole. In order that the dimensions of all insoles which aretrimmed with the aid of the pattern 14 shall be the same with regard tothe relation of the sewing-rib to the edge of the insole, the pattern 14is so constructed that an insole placed thereon by the operator will belocated with its margin projecting beyond the edge of the pattern therequisite amount to properly determine the desired relation of the soleedge to the sewing-rib. To this end, the upper face of the plateconstituting the pattern is recessed or cut away, as indicated at 70,(see also Fig. 7 to receive the sewing-rib of the insole. The recess 70is cut to a depth slightly greater than the height of the sewing-rib andextends across the upper face of the pattern plate from toe to heel andfrom one lateral margin to the other, leaving an endless flange 72projecting upwardly from the margin of the pattern. The upper edge ofthe flange 72 provides a flat face 74, adapted to engage the feather ofthe insole to support the insole during the trimming operation. In orderthat the marginal flange 72 of the pattern shall engage and properlysupport the moulded portion of the feather about the toe of the insole,the corresponding portion of the flange is built 1 up above the plane ofthe upper edge of the remaining portion thereof to provide a raised solesupporting face 76. A pair of holes '17 8 extend through the patternfrictionally to receive a pair of short pins (Fig. 9) which projectvertically from heads 82 at the upper ends of the pattern supportingposts 16.

h The clamp 24, as best shown in Figs. 4, 5, 6 and 9, is mounted on theclamp-carrier 26, in parallel relation to the pattern 14,

and consists of a plate having the same marginal contour as the pattern.The lower side of the clamp plate 24 is adapted to engage the unribbedface of an insole which is supported upon the pattern and to press theinsole against the upper edge faces 74 and 76 of the marginal flange 72on the pattern. To accommodate the moulded portion of the sole margin orfeather about the toe of the insole, the marginal portion about the toeof the clamp plate is cut away or rabbeted to form a sole engaging face84 (Figs. 4 and 5) that is complemental to the face 7 6 on the pattern.As the clamp is moved by the depression of the foot treadle 36, to bringthe clamp into work-engaging position, the lower side of the clampengages the unribbed face of the insole throughout the entire surface ofthe latter and securely clamps the margin of the insole against thepattern.

The clamp-carrier 26, as best shown in Figs. 9 to 12, inclusive,comprises a substantially rectangular frame having elongated upper andlower walls 86 and short end walls 88. The front side of theclamp-carrier frame is open while the rear side thereof is partiallyclosed by longitudinal webs 90. Rising vertically from the upper wall 86of the clamp-carrier is a tongue 92 which is received in a transverseslot 94 at the lower end of the slide 28. The clamp-carrier 26 ispivoted to the slide 28 by means of a hori zontal pin 96 which extendstransversely through the tongue 92 and through the forked lower ends ofthe slide. To insure rigidity of construction of the clamp-carrier 26,the carrier is strengthened by a pair of ribs 97 which extend outwardlyin opposite directions from the tongue 92 along the outer face of theupper wall 86. The carrier is further reinforced by means of the websand also by a transverse web 98 which connects the central portions ofthe upper and lower walls 8.6.

The clamp-carrier is normally maintained in a fixed position, relativelyto the slide 28 upon which it is pivoted, by means comprising a pair ofpins 100 (Figs. 9, 10 and 12) which are supported upright in guideways102 in the tongue 92, with the fiat upper ends of the pins engaging thetop wall of the slot in the lower end of the slide 28. The guideways 102are arranged inthe tongue 92 upon opposite sides of the hole throughwhich the pivot pin 96 extends, the guideways consisting of holes whichare bored through the tongue perpendicular to the upper end facethereof. The pins 100 are. sustained in the guideways 102 by means, ofscrews 104 which are screwed into the clamp-carrier frame from the rearside thereof and are provided with cone-shaped inner ends that severallyproject into the lower portions of the guideways 162 to engage acone-shaped surface 24 to frictionally support the clamp.

formed at the lower ends of the pins 100. The screws 104 may be loosenedto release the pins 100 and leave the clamp-carrier free to turn uponits pivot pin 96 as the clamp 24 is angularly adjusted with respect tothe slide.

The clamp 24 is supported above the pattern 14 by means of clampsupports 108 (Figs. 9, 11 and 12) comprising cylindrical blocks eachhaving a short pin 110 projecting axially from one end face and ascrew-threaded stud 112 projecting axially from the opposite end facethereof. The pins'110 are adapted to fit tightly within a pair of holes114 in the clamp The clamp supports 108 are secured to the lower wall106 of the clamp-carrier with provision for adjustment toward and fromeach other, and also for a certain amount of adjustment transversely ofthe clamp-carrier for purposes which will hereinafter be explained. Tothis end the studs 112 extend through longitudinal slots 116 (Fig. 10)in the lower walls 86 of the clamp-carrier, these slots being wider thanthe diameter of the studs to permit 0 adjustment of the clamp supportstransversely as well as longitudinally of the clamp carrier.

The clamp supports 108 are secured to the clamp-carrier by means of nuts118 which are provided on the free ends of the studs 112, a washer 120,large enough to overlap the side walls of the respective slot 116, beinginterposed between each nut 118 and the adjacent face of the lower wall86 of the clamp-carrier. The adjustment and clamping of the clampsupports 108 is further facilitated by means of a pair of washers 122which are severally interposed between the upper end faces of the clampsupports 108 and the adjacent face of the lower clamp-carrier wall 86.The upper face of each washer 122, as best shown in Fig. 13. is providedwith a pair of tongues or ribs 124, which are diametrically arranged onopposite sides of the central opening in the washer and which areadapted to fit within the longitudinal slots 116 in the clamp carrier.The upper face of each clamp support 108 is provided with a pair oftongues or ribs 126 which radiate from diametrically opposite points onthe stud 112. These tongues 120 fit into grooves 128 which are formed inthe lower face of the washer 122 and diametrically disposed on oppositesides of the opening in the washer, these grooves '1' extending in adirection perpendicular to the length of the ribs 124. The centralopenings in the washers 122 are elongated in a direction perpendicularto the length of the ribs 124, as indicated at 130 in Fig. 13, to permitrelative movement between the washers and the clamp supports in saiddirection. lVith this construction, the washer 122 is free to move inthe lon itudinal slots 108 but is prevented by the tongues 124 frommoving transversely with relation to the clamp-carrier. The elongatedhole in the washer 122 and the tongueand-slot connection between theclamp supports and the washers 122, however, permit the clamp supportsto be shifted relatively to said washer in a transverse direction withrespect to the clamp-carrier.

It is desirable that the edges of the pattern 14 and the edges of theclamp 24 shall be in exact alinement when the clamp is in workengagingposition so that the clamp will properly engage the margin of theinsole, particularly where said margin is moulded around the toe, andalso to prevent possibility of interference by the edge of the clampwith the proper guidance of the rounding knife by the pattern. It isalso desirable that the sole margin shall be pressed against the patternuniformly throughout the length of the former to insure that the insolewill not slip under the pressure of the rounding knife.-

Accordingly, it is desirable to make certain setting-up adjustments ofthe clamp whenever the pattern and clamp are replaced by others of adifferent size or style. This preliminary adjustment of the clamp iseffected in the following manner: The pat tern is first placed inoperative position upon the pins 80 carried by the pattern supportingposts 16. A clamp of a size corresponding to that of the pattern isplaced on top of the pattern and manipulated by the operator until theedge of the clamp is brought into exact alinement with the edge of thepattern. The screws 104 and the nuts 118 having first been loosened toleave the clamp-carrier free to tilt slightly with respect to the slide28 and to permit the clamp supports 108 to be readily shifted in theslots 116, the clampcarrier is then moved downwardly by depression ofthe foot treadle until the pins 110 upon the clamp supports 108 arebrought into engagement with the upper face of the clamp. Inasmuch asthe holes 114 in clamps of different sizes are located atdifferentdistances from each other, it is necessary to adjust the clamp supports108 toward or from each other in the slots 116 to bring the pins 110into position for engagement with the holes in the clamp. If the pinscannot be brought into exact registry with the holes in the clamp plateby this adjustment, the clamp supports 108 may be shifted transverselywith respect to the slots 116 sufficiently to permit the pins toregister with the holes. After the pins have been brought into registrywith the holes in the clamp plate, the foot treadle is further depressedto cause the pins to be projected into the holes and to press the clampfirmly against the pattern. Under the influence of this pressure, theclamp will readily and accurately adjust itself to bring itssole-engaging faces into the planes of the corresponding sole-engagingfaces of the pattern. lVhile the pressure is still maintained upon theclamp, the screws 104 are tightened to press the pins 100 against theslide 28 and thus rigidly secure the clamp-carrier to the slide in itsadjusted position relatively to the latter. The nuts 118 are alsotightened to secure the clamp supports 108 in their adjusted positionsin the slots 116 of the clamp-carrier. The clamp, which is thenpermitted to return to its normal elevated position, has been soadjusted relatively to the pattern, that it will thereafter cooperatewith the latter properly to clamp the insole which fits the pattern forthe trimming operation.

lVhile the clamp is descending into workengaging position, the requiredjig-holes are punched through the heel-seat of the insole. In theconstruction shown, the jig-holes are produced by means of a pair ofdies or punches 134 (Figs. 3, 5 to 7 and 9) which are mounted on thepattern and are arranged to cooperate with a cutting-block 136 (Figs. 4to 7) on the clamp, as the clamp moves toward the pattern. It is to beunderstood, however, that the present invention is not limited topunches which are mounted upon the pattern or to a cutting-block carriedby the clamp. The punches 134 are located on the center line of the heelportion of the pattern at the required distance from the rearextremity'thereof. The lower ends of the punches are set into holes 138which extend through the pattern. Each punch is provided with anexternal annular flange 140, which is seated against the recessed upperface of the pattern to support the punch against the pressure of thecutting-block. The cutting edges of the punches are located above theplane of the upper edge faces 74 of the flange 72 on the pattern, adistance equal to the thickness of the insoles which are to be opera-tedupon so that the punches will not interfere with the clamping action ofthe clamp 24 but will be adapted to cut completely through the insolematerial when the insole has been clamped against the pattern.

The cuttin-g'block 136 is set into the clamp 24 with its lower faceflush with the lower face of the clamp. The cutting-block is preferablyconstructed of soft metal which will withstand repeated cooperation withthe punches without injuring the cutting edges of the latter. The hole114 at the heel end of the clamp 34, which receives the pin 110 of therespective clamp support 108, eXtends through the cutting-block topermit said pin to project its entire length into the clamp.

hen an insole has been positioned upon the pattern 14 with itssewing-rib received in the recess 70, the heel-seat portion of theribbed face of the insole will lie in contact with one or both of thepunches, as indicated in Fig. 5-. WVhen the clamp is brought down, theheel-seat portion of the insole is forced down over the punches and thejig-holes are thus produced. The scrap cut by the punches is pushed downthrough the interior of the punches, as successive insoles are operatedupon, and this scrap is finally discharged from the punches and fallsbeneath the pattern. By means of the strengthening ribs 90, 98, aclamp-carrier of extremely rigid construction is provided, thus insuringagainst possible upward yielding movement of the heel end of the clampas the cutting-block 136 presses the insole against the punches 134.

After the insole has been clamped against the pattern and the jig-holeshave been punched through the heel seat of the insole, the roundingknife 40 is actuated to trim the sole margin which projects beyond theedge of the pattern. It has been found in operating upon laminatedinsoles that the margins thereof are not always stiff enough to permit arounding knife of the usual construction to cut in from the edge of theinsole to a point where the knife engages the edge of the pattern, as isthe custom in rounding leather soles. To avoid the necessity of cuttingin from the edge of the insole at the start of the trimming operation,the rounding knife 40, with which the illustrated machine is provided,has embodied therein a certain novel feature of construction whichenables the knife to penetrate the sole margin from one face instead offrom the edge thereof.

The rounding knife is illustrated in detail in Fig. 8. As therein shownthe knife comprises a blade having a vertical cutting edge 142; Theblade of the knife is thicker at its lower end to provide a base 144which is adapted to be clamped in the usual manner to the knife holder46, as illustrated in Fig. 2. The upper end of the knife 40 is beveled,as shown clearly'in Fig. 8, to produce a sharp point 146 for piercingthe insole material as the insole is forced down over said point.

In accordance with the usual practice, the trimming knife is retractedfrom the pattern to permit another untrimmed sole to be placed upon thepattern with its margin overlapping the edge. In the operation of thepresent machine, the trimming knife is normally held against the edge ofthe pattern not only throughout the trimming operation but it ispermitted to remain in contact with the pattern after the sole has beentrimmed. When the clamp 24 is brought down upon the sole throughpressure on the treadle 36 the portion of the margin of the insole whichprojects above the point of the rounding knife will be forced down overthe knife until the knife cuts completely through the margin. The knifeis then in position for commencing the trimming cut as soon as theinsole is clamped without the necessity of cutting in from the edge ofthe insole. At the completion-of the and arrangement of parts hereinshown and described, it will be understood that this construction andarrangement is not essential except so far as specified in the claimsand may be changed or modified without departing from the spirit andtrue scope of the invention.
